NAME¶
dh_systemd_start - start/stop/restart systemd unit files
SYNOPSIS¶
dh_systemd_start [
debhelper options]
[
--restart-after-upgrade] [
--no-restart-on-upgrade]
[
unit file ...]
DESCRIPTION¶
dh_systemd_start is a debhelper program that is responsible for
starting/stopping or restarting systemd unit files in case no corresponding
sysv init script is available.
As with
dh_installinit, the unit file is stopped before upgrades and
started afterwards (unless
--restart-after-upgrade is specified, in
which case it will only be restarted after the upgrade). This logic is not
used when there is a corresponding SysV init script because invoke-rc.d
performs the stop/start/restart in that case.
OPTIONS¶
- --restart-after-upgrade
- Do not stop the unit file until after the package upgrade has been
completed. This is different than the default behavior, which stops the
unit file in the prerm and starts it again in the postinst
maintscript.
This can be useful for daemons that should not have a possibly long downtime
during upgrade. But you should make sure that the daemon will not get
confused by the package being upgraded while it's running before using
this option.
- -r, --no-restart-on-upgrade
- Do not stop service on upgrade.
- --no-start
- Do not start the unit file after upgrades and after initial installation
(the latter is only relevant for services without a corresponding init
script).
NOTES¶
Note that this command is not idempotent.
dh_prep(1) should be called
between invocations of this command (with the same arguments). Otherwise, it
may cause multiple instances of the same text to be added to maintainer
scripts.
Note that
dh_systemd_start should be run after
dh_installinit so
that it can detect corresponding SysV init scripts. The default sequence in
dh does the right thing, this note is only relevant when you are
calling
dh_systemd_start manually.
